M=-2 and (x¹ , y¹ ) = (0 ,4 )

y-4/x-0 = -2
y-4 / x = -2
y-4=-2x
y=-2x+4 this is the slope intercept form

and this is the standard form
-2x+y=4 or 2x-y=-4

Which are the x-intercept and y-intercept of the line drawn through the points A and B?
ladessa [460]
First you have to figure out what the equation of the line is. Let's use the slope formula to find the slope, and then one of the points to find the y-intercept. We'll put the line's equation in y=mx+b form.

slope =  \frac{ y_{2} -  y_{1}  }{ x_{2} - x_{1}  } \\ slope = m \\ m =  \frac{5 - 1}{-7 - 1} \\ m =  \frac{4}{-8} \\ m = - \frac{1}{2}

Now, we'll use that slope in y=mx+b form with one of the coordinates in order to find what b (which is also the y-intercept) equals
y = - \frac{1}{2}x + b \\ 1 = 1(- \frac{1}{2}) + b \\ 1 = - \frac{1}{2} + b \\ 1 \frac{1}{2} = b

therefore your y-intercept is equal to 1.5. In order to find the x-intercept we'll take our new equation y = - \frac{1}{2} + 1 \frac{1}{2} and make y = 0, because the line intersects with the x-axis when y is equal to zero.

y = - \frac{1}{2}x + 1 \frac{1}{2} \\ 0 = - \frac{1}{2}x + 1 \frac{1}{2} \\ -1 \frac{1}{2} = - \frac{1}{2}x \\ x =  3

therefore, your x-intercept is 3 and your y-intercept is 1.5

Ilia_Sergeevich [38]

Answer:

A. 4,800 feet below sea level

Step-by-step explanation:

10,000 feet below sea level = -10,000 feet

"rises 5,200 feet" = +5,200 feet

=-10,000 + 5,200 = -4,800 feet

=4,800 feet below sea level.

puteri [66]
You use long division when you divide polynomial by other polynomials. You use synthetic division to divide polynomials by binomials of the form (x-k).
